Application filed January 21,1907. Serial No. 353.232.

Be it known that we, ALEX II. GRANT and MILTON N. GRANT, citizens of theUnited States, residing, respectively, at Middleport and Columbus, inthe counties, respectively, of Meigs and Franklin and State of Ohio,have invented certain new and useful Improvements in Devices for MakingOrnamental Brick, of which the following is a speciiica- IO tion.

Our invention relates to a device for malring ornamental lricl, and hasfor its object the provision of a device of this character adapted toroughen the surface of a mass of i 5 clay as it is forced from the dieof a brickmaking machine.

Further objects and advantages of the invention will be set forth in thedetailed descrip tion which new follows.

In the accompanying drawings, Figure 1 is a side elevation of a portionof a briclemalring machine having our invention applied thereto. Fig. 2is a plan view of the parts illustrated in F 1; and Fig. 3 is anenlarged view of a portion of the structure illustrated in Fig. l,showing our improvements applied thereto and in section.

Like numerals designate corresponding parts in 4all of the figures ofthe drawings.

Referring to the drawings, the numeral 5 designates the die portion of abrick-making machine, andthe numeral 6 designates the mass of clay whichis forced therefrom. As this clay leaves the mouth of the machine it issupported by an endless belt 7, which passes over a pulley 3 and rollersQ. These rollers are supported by a frame 10.

In carrying out our invention `we secure two upstanding supports l1 uponthe opposite sides of the frame 10. Pivoted between these supports, asat 12, is a plate 13, the free edge 14 of which is held into engagementwith the upper surface 15 of the mass of clay by springs 16, saidsprings being carried by a rod 17, and the lower ends of said springsengage studs 13, which are formed upon the upper face of the plate 13. Apulley 19 is mounted upon a shaft 2O and is adapted to impart movementto said shaft when power 5o is applied thereto. Secured to the shaft 20is a vibrator 21, which comprises a plurality of lugs 22, the ends ofwhich are adapted to engage the under surface of the plate 13 to imparta rapid vibratory movement to said plate. A transverse rod 23 forms astop to limit the downward movement of the plate.

Frein the foregoing description it will be readily understood that whenthe shaft 20 is rotated the lugs 22, striking against the under side ofthe plate 13, impart a rapid upand-down movement to the free. edge 14 ofi said plate, which will consequently roughen the upper surface of theclay.

Frein the foregoing description it will be seen that simple andefficient means are here in provided for acconiplishing the objects ofthe invention g but while the elements shown. and described are welladapted to serve the purposes for which they are intended it is to beunderstood that the invention is not lime ited to the preciseconstruction set forth, but includes within its purview such changes asmay be made within the scope. of the appended claims.

What we claim is-w 1. In a device of the character described, thecombination with a machine adapted to discharge a continuousmass of claytherefrom, of a plate pivoted above said mass of clay, and thefree edgeof which engages the face of said clay, and means for imparting l rapidvibratory movement to said plate.

2. In a device of the character described, the combination with amachine having a die through which a continuous mass of clay isdischarged, of a plate pivoted at an angle above said clay, the freeedge of said plate being opposed to the movement of said clay, and arotative member adapted to impart rapid vibratory movement to saidplate.

3. In a device of the character described, the combination with amachine having a die through which a continuous mass of clay isdischarged, of a plate pivoted at an angle above said clay, the freeedge of said plate being opposed to the movement of said clay, arotative member adapted to impart rapid vibratory movement to saidplate, and spring means for holding the plate into engagement with theclay.

4. In a device of the character described, the combination with aconveyer adapted to support a moving mass of clay, of a frame, a platepivoted at one edge in said frame and above said mass of clay, the freeedge of said l plate engaging the upper surface ofthe mass IOO of clay,spring means for holding the `free parting rapid vibratory movement tosaid edge of said plate into engagement With the member to therebyroughen the face of the mass of clay, and a rotative member adapted massof clay. to impart a rapid vibratory movement to Tn testimony Whereor`We aliX our signa- 5 said plate. tures in presence of two Witnesses.
